BATTERY-roer CLAMP.

Application lerl April 1,

To all whom t may camcom:

Be it known that I, HARRY L. Woon, a citizen of the United States, residingat Lakewood, in the. county ofV Cuyahoga and State of Chio, have invented a certain new and useful improvement in Battery-Post Clamps, of which the followingis a fulll clear, and exa-ct description, reference being had to thc accompanying drawings.

This invention relates to an apparatus which is adapted for use in connection with the sealing of battery posts to jar covers, 'and has for one of its vobjects the construction of a device for enabling battery jars to-'be sealed in accordance with the method'set forth in my copending application No.

453,927, sled Mar-@h ai, 192i.

My invention is more particularly con-r cerned with the provision of a portable hand actuated clamp which is well adapted for usev in service stations for positioning the posts and cover in proper relation to each other and then applyingpressure, whereby the posts may be built up-to the finished size while pressure is being applied. To this end, my invention is directed toward the construction of a clamp which is simple in construction and capable of use on all sizes of jars to be sealed. Y

The means for carrying out my invention will be fully set forth in the following description which relates to the drawings andthe essential characteristics of my invention will be summarized in the claims.

ln the drawings, Fig. 1 is a plan view of a clamp constructed in accordance with my invention; Fig. 2 is a side elevation thereof; Fig. 3 is a vertical section-taken through the clamp on the line of Fig. 1 and show ing the battery jar cover in position on the platen with the clamping jaws unlocked; and F ig. l is a similar section showing the jaws locked to the cover and posts.

Designating the parts shown in the drawings by the use of reference characters, 10 indicates a base, 11 a standard, and 12 the platen or lower jaw `of a clamp which is adapted to support a pairv of battery posts and'ftheir associated grids. As indicated in F ig. 2, the platen may be provided with recessed portions 13 extending longitudinally thereof for positioning the battery posts 14E laterally to bring them into registration with the cover 21 prior tothe building-up process. The upper jaw of the clamp is shown at 15 as an overhanging plate rigidly i922. saranno. 548,864.

secured to al post 16, which is vertically movable within a tubular opening 17 inthe standard 1'1; a springlS being positioned at the bottom of: the opening for normally holding the post 16 and its attached jaw 1'5, out of Contact with the j ar cover to be sealed'.

F or enabling pressure to be lapplied against the battery posts and cover, I'pro vide a handle 20 which is rigidly secured to the post 16, and is so positioned thereon thaty the jaw 15 may be quickly 'brought into encover-between the jaws, I have 'shown a spindle 25 which is freely movable within the jaw 15 and which is threaded, as at 26, to engage a threaded opening 27 in lthe platen 12. The upper end of the spindle is provided with a crank 28, having a handle 29 attached thereto, wherebythe jaws may be quickly clamped to hold the posts 14 together with the removable ringsl 30, securely to the cover 21. 1 Y y The method of sealing posts to a cover, as described and claimed in the above mentioned application, embodies briefly, the bringing of a rring 30 into engagement with the cover 21, and overv the post V14, and then while pressure is being applied, to unite the ring and post and finally build it upl tothe finished thickness. Accordingly to provide a form of mold for enabling the post to be built up, and at the-same time construct a clamp capable of gripping all sizes of posts,

I have shown the jaw 15 ashaving openings arranged in pairs, and of different sizes, as at 32 and 33 respectively.- ln addition, l have shown post building molds 3st which are positioned within the openings 33, and which are adapted to be madeintegral with the jaw,

or to be removably held therein as desired.

ln operating a clamp constructed according to my invention', the post-s and cover to be sealed, are placed onr the platenf12, and the rings 3() positioned over the post openings in the cover and beneath the openings in the jaw 15. Then the jaw 15 is brought' into engagement with the rings 30hy press'- ing do-wn upon the handle 20 until the jawv engages the top of the co-ver,whereupon theV A up to the finished size. The posts are built Y blow-torch, before the molten metal is addedv up to the required size by the addition oi lead in a molten state within the .post opening-in the mold. Usually the Vexposed surface of the severed post is Yheatedv as by a to obtain a firm bondV with the added material. Y f Y,

VA lamp constructed according to my invention V-is well adapted Afor use in garages or serviceV stations, because oi' the .tact that it is light in weight, portable, capable ot receiving all'sizes of posts,and for holding them securelyvduring the sealing operation.

The arrangement of the parts enables the postsytogether with the associated grids, to

be readily positioned on the platen, :and

thereafter `clamped tothe cover with the expenditure of slight effort, and in addition permits the rsealed members to be quickly released. Y Y

.Having thus described my invention, l claimz- Y LVA battery post clamp comprising in combination, apair of jaws, one of which is Vmovable,one ot' said jawsbeing shaped to hold a pair ot posts and to position them laterally for receiving a battery' cover, and means for moving one' of said aws to clamp thepost and cover between said jaws.
